This article will describe the main features of the MicroProfile Fault Tolerance specification and then demonstrate how it was implemented in WildFly Swarm, the Red Hat MicroProfile implementation.

this is an introduction to Istio. Istio helps automate the developer time to implement a feature. The combination of code complexity and code heft (i.e. number of lines of code) can put a drag on an implementation. Istio is a better way.

Learn about cloud native architecture, including principles and techniques for building and deploying Java microservices via Spring Boot, Wildfly Swarm and Vert.x.

Last week, Red Hat was present at the SnowCamp conference in Grenoble, France. The SnowCamp is a technical conference held in Grenoble and proposing a unique combination of deep dive sessions (universities), technical talks and a last day on the slopes.

This article would help to configure http2 protocol support for the camel-undertow component. Camel's undertow component use embedded undertow web-container of version undertow-core:jar:1.4.21. This version also supports the http2 connection. I have used camel version 2.21.0-SNAPSHOT from upstream https://github.com/apache/camel. Also, the curl version to test application using camel-undertow component is 7.53.1. This curl version supports --http2 flag for sending an http2 request. I have also used nghttp to test application from linux terminal. However, this article is not about http2...

At the beginning of October, I attended JavaOne in San Francisco to present on WildFly Swarm and Apache Kafka. For those of you that weren't able to attend the session, or for those that did and saw first hand the issues with the demo, I will be covering all the details of how the demo should work! The presentation material that was presented at JavaOne can be found here, and all the code for the demos is in GitHub. MiniShift...

Let’s dive right in! In the previous post (part I), we set up the context for this blog. Basically, as we introduce a strategy to bring microservices to our architecture, we cannot and should not disrupt the current request flows. Our "monolith" applications typically provide a lot of value for the business and we must drive down the risk of negatively affecting these systems as we iterate and expand. This leads us to an often-overlooked fact: when we start to...

Quick interlude to my last blog. As part of my last blog on low-risk monolith to microservice architecture, I made this statement about microservices and not doing them: “Microservices architecture is not appropriate all the time”. I’ve had some interesting reactions. Some of it along the lines of “how dare you”. I also poked at that a bit on Twitter a month or so ago Let me expand a little bit. Doing microservices, or monoliths, or SOA, or Microliths or...

Eclipse MicroProfile (MP) aims at bringing Microservices to Enterprise Java by developing common standards that MP-compliant vendors then implement [1]. This not only applies for developer APIs but also to interfaces for running, configuring, and managing the servers. The more classical specifications have often left out many details as vendor-specific - especially in the area of setting up and running of the applications and servers. For the Java Enterprise Edition, there are standards like JMX and JSR-77, but those were...

We hear about Microservices a lot nowadays. Its implementation requires us to deal with new challenges. A key question that comes with using microservices is how to handle interactions in an asynchronous way. The answer to that is messaging. Among other things, messaging features the following: Loose coupling since it decouples client from services. Improved availability since the message broker buffers messages until the consumer is able to process them. Supports a variety of communication patterns including request/reply, notifications, request/async...

As part of a two-day microservices workshop I’m putting together, I’ve been thinking a lot about how to explain monolith-application decomposition and what a transition to microservices might look like. This is a small subset of that material, but I want to share it with you to get feedback (in the workshop we go into more detail about whether you should even break up your monolith). I base this on my own tried and true real-life experience as well as...

At the upcoming JavaOne 2017 , which is being held at the Moscone Center in San Francisco, CA during October 1-5, we will be hosting a session on transactions for microservices. In this session, Mark Little and Tom Jenkinson will present the subject of "Transactions for Microservices? Really?" . We shall give an overview of the topic, including useful information on transaction models, which can be appropriate for use in microservice architectures. This will be followed by a live coding...

This blog to help my fellow developers who are working on "Docker" and " Kubernetes" simultaneously. Because, they know that Kubernetes runs over docker-engine but there is a catch, that: 1. Containers running on Docker, and 2. Containers running inside of a Kubernetes Pod, are absolutely running isolated, without even knowing each other's existence. But, we are developers, so there are chances where we might come across a situation where we desperately need to let the Docker formatted containers communicate...

Creating, associating, and using a database with a MicroProfile-based microservice In this blog post, I will cover how to create, populate, and associate a database to your MicroProfile-based microservice. I will also cover how to modify your microservice so that it makes use of the database. This is the continuation of the " A MicroProfile-based microservice on OpenShift Container Platform - Part 1; Creating a simple MicroProfile-based microservice and deploying it to OpenShift Container Platform" blog post and it assumes...

Microservices is probably one of the most popular buzz words among my fellow developer friends, and I do like the concept of being flexible, agile and having simply having more choices. But as a person that worked in the software integration space for years, I started to see some resemblance of the old ESB days. Looking at the problem from ten thousand feet up. A decade ago, we had to come up with a better way of organizing the spaghetti...

The pace of Java EE releases has been slowing and has been unable to adapt to the rapid rise of microservices. MicroProfile was created as a means to collaborate with vendors, individuals, and organizations like Java user groups in an open forum, to rapidly bring microservices to traditional Java EE developers. We moved the project to the Eclipse Foundation and have officially renamed it Eclipse MicroProfile. Red Hat is implementing MicroProfile specifications via WildFly Swarm and optimizing it for use...

Securing Microservices using JSON Web Tokens (JWT) and Red Hat SSO, by Thomas Qvarnstrom

One question, which is often asked of me is “How do I quickly get new features into production?” This is the whole idea of microservices, to quickly move features into production. At this year’s Red Hat Summit, I spoke to this during my OpenShift Application Runtimes session, introducing it as an upcoming product. I spoke on integrating language runtimes into OpenShift and Kubernetes so that as you write Microservices you can leverage a lot of the features that are available...

Getting up and running with local development for Red Hat Mobile Application requires that you run MongoDB and Redis locally. Doing so isn’t particularly difficult if you follow online guides, but it would be much more straightforward if you could just get these pieces of software up and running in a single command and not need to worry about versioning, creating data directories, setting permissions, and compiling some things such as Redis from source. It would be even better if...

In a previous blog post, we explained how to deploy an existing JBoss BRMS/Drools rules project onto an OpenShift DecisionServer. We created a decision/business-rules microservice on OpenShift Container Platform that was implemented by a BRMS application. The polyglot nature of a microservice architecture allowed us to use the best implementation (a rules engine) for this given functionality (business rules execution) in our architecture. The project we used was an existing rules project that was available on GitHub. We did however...
